According to an El Pais report, Spain is said to be seriously considering taking its Gibraltar dispute with Britain to the United Nations (UN). A recent row between the two countries recently flared up when an artificial reef being built on the territory threatens to block Spain's fishing vessels.

Spain shows no indications of a request to the UN for the Britain to give up its claim to the territory or to observe to definite settlements. Apparent plans to take the issue to the UN's higher court could escalate hostilities between the two countries. 

Earlier reports on the El Pais newspaper says a source confirms of Spain going to the UN for support. And presenting the issue is one of the options Spain may take. Spain's Prime Minister, Mariano Rajoy, is set to visit Argentina in September. Exchange of ideas with Argentina, who is currently serving a term in the UN, would be likely.

In the meantime, Spain's stricter vehicle checks continue to cause long lines in the border for both travelers entering and leaving the territory.
